Abstract

<B>"COMPOSIçãO DE ELASTÈMERO TERMOPLáSTICO COM REOLOGIA MODIFICADA SUBSTANCIALMENTE LIVRE DE GEL, PROCESSO PARA PREPARAçãO DA COMPOSIçãO E ARTIGO MANUFATURADO"<D>. A presente invenção refere-se a composições de elastómero termoplástico com reologia modificada por modificação por peróxido de uma mistura fundida de um polímero EAO ou uma mistura de polímero EAO e um polímero de alta fusão tal como polipropileno ou um copolímero de propileno/(-olefina. As composições resultantes possuem uma fase elastomérica, uma fase não-elastomérica e certas propriedades físicas que excedem as de uma composição similar que não tenha sua reologia modificada ou da mesma composição antes da modificação de reologia. As composições podem ser utilizadas na fabricação de uma série de artigos de manufaturas, tais como peças automotivas, peças não-automotivas, membranas de forro e canos de botas, através de procedimentos convencionais.
